PROBLEM TO BE SOLVED: To provide a hermetic compressor capable of discharging and supplying a gas from which an oil is sufficiently separated to the outside of a closed container even if a gas flow velocity and a gas flow rate are large during a high-speed operation. SOLUTION: An impact plate 24 at the outlet of a compression mechanism rise communication passage 21 is disposed so as to cover the outlet of the compression mechanism rise communication passage 21 to collide a refrigerant gas 2 against the impact plate 24. The opening direction of the impact plate is positioned roughly vertically to the outlet of the compression mechanism rise communication passage 21 and roughly circumferentially along the closed container 12. Consequently, even when the gas flow velocity and the gas flow rate are large during the high-speed operation and a separating ability is not sufficient merely by the use of a centrifugal force due to the swing of a rotor 8a, the refrigerant gas 2 from which the oil 4 is sufficiently separated can be discharged and supplied to the outside of the closed container 12.
